Lubricating oil composition

본 발명에 따른 윤활유 조성물의 다이에스테르계(diester) 베이스 오일은 중심원자를 기준으로 한쪽의 에스테르기에 결합된 알킬기 체인(chain)이 다른 에스테르기에 결합된 알킬기보다 탄소수가 2개 더 많은 비대칭 구조를 갖는다. 이에 따라, 윤활유 조성물의 점도가 낮으며, 고온에서의 증발량이 상대적으로 적음으로써, 소형 하드디스크 모터에 사용하는 경우 전력소모량을 감소시킬 수 있으며, 고온에서의 안정성을 향상시킬 수 있다. The diester base oil of the lubricating oil composition according to the present invention has an asymmetric structure in which the alkyl group chain bonded to one ester group based on the central atom has two carbon atoms more than the alkyl group bonded to the other ester group. . Accordingly, since the viscosity of the lubricating oil composition is low and the amount of evaporation at a relatively high temperature is relatively low, when used in a small hard disk motor, power consumption can be reduced, and stability at high temperature can be improved.

Production of renewable base oil and diesel by pre-fractionation of fatty acids

The present invention relates to the field of hydrotreatment of biological oil, in particular to methods for producing renewable base oil and a diesel oil from low-value biological oils. It was found that low-value biological oils containing free fatty acids and fatty acid esters can be processed into a renewable base oil and a renewable diesel oil in an efficient manner by first separating at least part of the saturated free fatty acids from the feedstock and then processing separately this saturated free acid feed in a ketonisation reaction followed by hydrodeoxygenation and hydroisomerisation reactions to yield a renewable base oil stream. The remaining free fatty acid depleted feed may be processed in a separate hydrodeoxygenation and hydroisomerisation step to yield a renewable diesel stream. Splitting the feedstock into two separate streams, where one is a saturated free fatty acid stream provides surprising advantages compared to a combined treatment of the entire feedstock.

PAO 는 윤활제의 성분과 같은 많은 유용한 적용성을 갖는다. One or more oligomers of the olefins are prepared in the presence of a single site catalyst. Preferably the olefin is an α-olefin and the oligomer is a poly-alpha-olefin (PAO). The draft PAO is completely or substantially free of tertiary hydrogen due to isomerization. As a result, PAO has improved biodegradability, improved antioxidant activity and / or relatively high viscosity index. PAOs have many useful applications, such as components of lubricants.
